Abstract

L'invention porte sur un appareil générateur d'énergie qui concerne le domaine technique d'une nouvelle énergie propre, et concerne plus précisément le domaine technique de l'énergie éolienne. L'appareil générateur d'énergie comprend une turbine éolienne (1), une unité de commande (2), un module d'accumulation d'énergie (3), un onduleur (4), un alternateur (5) et un moteur électrique (6). L'onduleur est lié au module d'accumulation d'énergie et il est destiné à être utilisé dans la transformation d'un courant continu en un courant alternatif, en réalisant ainsi un équipement électrique possédant de la puissance de travail; l'onduleur permet un démarrage progressif du moteur électrique; et le moteur électrique est relié à un arbre de la turbine éolienne par l'intermédiaire d'un réducteur. Lorsque la charge électrique dans le module d'accumulation d'énergie atteint une valeur prédéterminée, le moteur électrique commence à travailler en même temps que le module d'accumulation d'énergie est en cours de charge, puis le moteur électrique entraîne la turbine éolienne en rotation, en évitant ainsi que la turbine éolienne ne s'arrête lorsque le vent faiblit pendant un certain temps. Ceci permet à la turbine éolienne de tourner en continu pour fournir de l'énergie électrique en permanence.
